Vintage Guinness ads are fantastic.
Having had problems with alcohol in my life, I don't like it in a literal sense, because alcohol is not always good for you. Most of the time, actually, not so. However, I see what they are getting at (don't worry, get messed up, have fun) and I wholeheartedly approve.
Back in the day, of course, beer
was the healthful temperance drink for clean living, at least in comparison to that
demon gin.
Which makes sense: it was low-alcohol, high-calorie (and hydration), a legitimately important source of nutrition for many rather than just an ethanol delivery source.
